[0019] figure 1 The flow chart of the prediction method of cold filter point of light diesel oil based on the concept of blending index is given. First, convert the units of each component oil of light diesel oil from Celsius to Fahrenheit, then obtain the volume blending index of each component oil, and then calculate by adding the cold filter point (Fahrenheit) of each component oil Cold filter point (degrees Fahrenheit) of light diesel oil. Finally, the cold filter point (Celsius) of light diesel oil is obtained by unit conversion.
[0020] The conversion relationship between Celsius and Fahrenheit is:
[0021] CPF i =CP i ×1.8+32
[0022] CPF i —Cold filter point of component i, unit: °F;
[0023] CP i —Cold filtration point of component i, unit: °C;
[0024] figure 2 The volume blending index curves of the component oils are given. The abscissa of the figure is the cold filter point value (°F) of the component oil, and the ordinate is the volume blending index...
